FIELD OF THE INVENTION

The present invention relates generally to a structure of assembledshelf, and more particularly to a structure of an assembled shelf thathas a vertical groove and bar to position the shelf and vertical siderack.

BACKGROUND OF THE INVENTION

Whether it is in a home or business place, an assembled shelf hasimportance, and through the deliberate efforts in the industry, it nowhas diversified structures. The current shelf can be divided into aone-piece structure and assembled structure. The main part of theone-piece structure is fixed; therefore, it cannot be taken apart. Themain part of the assembled structure is made of the separated components(such as the shelf and side racks). Therefore, it can be taken apart andrestored to its separated state. Currently, the assembled shelf iswidely accepted by the consumer because of its flexibility. However, thecurrent assembled structure still has the following issues:

1. The components of the current shelf must rely on some hardware (suchas screws, nuts) to be positioned; therefore, it must have a tool toachieve the assembling or disassembling. Because the parts of the shelfthat need hardware exceeds ten places, it is time consuming.

2. Moreover, if the shelf needs added structure, it must have multipleshelves or stack them on top of each other. Because there is no commonstructure between them, it lacks a stable connection, and the cost ishigh as well.

3. The weight limitation is limited when the shelf is being used, andthe shelf is unable to take objects that are too heavy. The commonsolution is to place a board or iron board between the boards or bars toachieve the objective; however, such a solution affects the entire lookof the shelf.

4. Most of the time, the conventional shelf places a layer board on theframe and is unable to secure the layer board, so that layer boardsometime flips, when it is under the outside force, lacking ofstability.

Thus, to overcome the aforementioned problems of the prior art, it wouldbe an advancement in the art to provide an improved structure that cansignificantly improve the efficacy.

To this end, the inventor has provided the present invention ofpracticability after deliberate design and evaluation based on years ofexperience in the production, development and design of relatedproducts.

BRIEF SUMMARY OF THE INVENTION

The improved fact of the present invention is described as follows:

1. It is applied so that the shelf and vertical side rack do not needother positioning components to achieve positioning, making the presentinvention more effective and practical.

2. The secondary bar provides the common vertical side rack commonlyused by the shelf, greatly reducing the cost for shelf and beingeconomical.

3. The reinforced stand is placed between the ⊂ shaped bars are tosupport the strengthen layer board, so that the shelf may hold heavierobjects, increasing the practicality.

4. The reinforced stand is assembled, so that the users can add parts.

5. Using the design of the insert groove formed by a bent slab to placethe groove over the two sides of the shelf plank, the layer board cannotbe lifted, which makes it more stable and beautiful. The bottom of theinsert groove protrudes inside more than the top. One end may beinserted into the insert groove on the one side, and the other end maybe inserted into the insert groove on the other side, making theassembly more convenient.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be morereadily understood upon a thoughtful deliberation of the followingdetailed description of a preferred embodiment of the present inventionwith reference to the accompanying drawings.

As shown in FIGS. 1-3, there is the first embodiment of the improvedstructure of assembled shelf. The main frame comprises two vertical sideracks 10 and several sets of shelves 20. A shelf is placed between thetwo vertical side racks 10, and the fixed frame (connected by welding)is the vertical side rack made by a vertical bar 30 and horizontal bar40. The horizontal bar 40 is placed on the pre-determined height of theshelf 20 for the shelf 20.

A vertical bar 30 of the vertical side rack 10 includes a main bar 31and an inner/outer secondary bar 32 33. The inner/outer secondary bar isplaced inside and outside of the main bar 31, and the main bar 31 isspaced between the inner/outer secondary bar 32 33. The space ispositioned and formed by the horizontal bar 40.

The sides of the shelf that are corresponding to the vertical side rackhas a frame 50, and a vertical groove 51 is placed between two ends ofthe frame. The position of the groove is connected with the inner secondbar 32 of the vertical side rack 10 mentioned above, and the surface 52of the frame is pushed against the side of the main bar 31.

Through the above structure and design, the shelf 20 and the twovertical side racks 10 do not need other positioning components andassisting tools to achieve positioning. Moreover, the outer secondarybar 33 provides extendable vertical side racks for the shelf as shown inFIGS. 3 and 4. When the present invention extends to another set ofshelves, it can just place another set of vertical side racks 10Bbetween the space of one side of a vertical side rack 10 of the originalside rack. Another shelf 20B is placed between that vertical side rack10B and the original vertical side rack 10, using the connection betweenthe groove 51 of the frame 50 and the inner secondary bar 32 inside thevertical side rack 10 to assemble the extension of the shelf. As shownin FIG. 5, there is a structure using the above mentioned principles toassemble a triple shelf.

As shown in FIGS. 6, 7, there is the second embodiment of the improvedstructure of an assembled shelf. The features of the shelf comprise twovertical side racks 10 and several shelves 20, being the same as thefirst embodiment mentioned above. Therefore, it is not repeated herein.

The difference is that a vertical bar 30 of the vertical side rack 10includes a main bar 31 and a secondary bar 31B. The main and secondarybar are placed in parallel and spaced in between, the space being formedby the horizontal bar 40.

The sides of the shelf 20 that are corresponding to the vertical siderack 10 have a frame 50. A vertical groove 51 is placed between two endsof the frame, and the position of the groove is connected with the mainand secondary bar 31 31B mentioned above.

Through the above structure and design, the shelf 20 and the twovertical side racks 10 do not need other positioning components andassisting tools to achieve the positioning. Moreover, the secondary bar31B provides an extendable vertical side rack for the shelf as shown inFIGS. 8 and 9. When the present invention extends into another set ofshelves, it can just place another set of vertical side racks 10Bbetween the space of one side of a vertical side rack 10 of the originalside rack. Another shelf 20B is then placed between that vertical siderack 10B and the original vertical side rack 10, using the connectionbetween the groove 51 of the frame 50 and the secondary bar 31B insidethe vertical side rack 10 to assemble the extension of the shelf forquick assembly.

On the other hand, with regard to taking apart the above mentionedstructure, the shelf 20 and its vertical side racks 10 may bedisassembled into its independent components. When taking it apart, oneend of the shelf 20 that has frame 50 is picked up, which makes thegroove 51 separate from the inner secondary bar 32. All shelves 20 maybe collapsed according to this operational procedure, so it is notrepeated.

The main bar 31 and the secondary bars 31B, 32, 33 of the vertical siderack 10 can be circular bars. The sectional surface of the groove 51 ofthe frame is semi-circular.

Among them, the application for the above mentioned embodiments is thatthe vertical section of the frame 50 by both sides of the shelf 20 canhave a ⊂ shape. Also, a reinforced stand 60 may be placed between theframe 50 on both sides, as shown in FIGS. 10, 11, 12. The reinforcedstand has a long board with predetermined width, and the top end of itsshort end extends as a horizontal surface. The reinforced stand 60extends a bent section 62 on both ends along the long end, so that thereinforced stand may stand from the short end. Thus, the ⊂ shaped frameon both sides of the shelf opens shelf plank 53, forming a frame space Abetween the bottom of the shelf plank to the bottom of the frame 50. Theframe space is for the bent section 62 of the reinforced stand 60 toinsert, so that the reinforced stand 60 is placed between the frame onboth sides. The top horizontal support 61 at the top side of thereinforced stand 60 supports the bottom of the layer board. By so doing,it forms a reinforced structure, so that the shelf plank 53 can handlegreater weight.

Among them, as shown in FIGS. 13, 14, 15, the frame 50 on two sides ofthe shelf 20 may have a bent slab 70. The top and bottom of the bentslab can be a horizontal slab 71, and a vertical slab 72 is connectedbetween the top and bottom to make the section of the bent slab 70 likea step. The top of the frame 50 on two sides of the shelf 20 form a bentedge 54, and the horizontal slab 71 of the top end of the bent slab 70is connected to the bottom of the bent edge 54.

By so doing, a ⊂ shaped insert groove 55 is formed at the bottom of thebent edge 54, and the end of the horizontal slab 71 at the bottom of thebent slab 70 sticks out at the end of the bent edge 54. The insertgroove 55 may be placed on both corresponding sides of the bent slab 70,so that the shelf plank 21 can be assembled. Therefore, the shelf can beassembled as different styles of shelf planks (as shown in FIG. 17) tomake the product more plentiful. The bottom of the insert groove 55protrudes inner more than top end, when it is assembling the shelf plank21, as shown in FIG. 16. After one end is inserted into the insertgroove at a tilted angle, inserting another side of shelf plank into theinsert groove on the other side is more effective.
